General Description
The KM4270 is a dual ultra-low cost, low power,
voltage feedback amplifier. At 5V, the KM4270 uses
only 160
μ
A of supply current per amplifier and is
designed to operate from a supply range of 2.5V to
5.5V. The input voltage range exceeds the negative
The KM4270 offers high bipolar performance at a low
CMOS price. The KM4270 offers superior dynamic
performance with a 4.9MHz small signal bandwidth
and 5.3V/
μ
s slew rate. The combination of low power,
high bandwidth, and rail-to-rail performance make
the KM4270 well suited for battery-powered com-
munication/computing systems.
